Jack having a child with Buttercup is just wrong. Why? Because he is twice her age! And as for whether any of this stuff will happen, I will honestly be disappointed if Walker doesn't have a son. I think all the rulers should have heirs.

I think Jack is around her father's age. I can't see it happening mainly because of the type of character Jack is. If Jack ever had a child, he'd love the woman, not mentor her.

That's basically the same reason I have for believing that Walker has child, ari-6. The other 4 realms leaders mentioned have kids. If Walker doesn't have a kid, I think he should at least have an heir of some kind.
